Washing the car is the new Thai-bo

My efforts to get to 85 kg by the time we returned home from our 250 day world odyssey (natandev.travellerspoint.com) were on track until we got called home early. Thanks to the plentiful supply of hearty food and slices I put on most of the weight I lost whilst away in a mere 3 weeks. That's not exactly true, I went from 106 down to 92 then back up to 97 and now I have equalized at about 95. I have been working on the last 10 kg but I don't seem to be making any progress. Concerned by my fruitless efforts I decided to consult Mr Fortnight Forta. In years gone by he would have recommended a hot cold pack but this time he gave me a very insightful run down of the ideal fat burning heart rate. It turns out I have been working a little too hard. I have been monitoring my heart rate whilst riding and found that I'm operating at 80 - 100 % of my MHR.


Researchers from Birmingham University's Human Performance Laboratory attempted to pinpoint the exercise intensities at which fat metabolism is maximised in a study of 18 male endurance cyclists with a training background of at least three years. Their work found that the Fatmax Zone is between 68% and 79% MHR.

Mountain biking keeps me in the fatmax zone for longer but it's still burning way too many sugars and not enough fat. After a ride today I forgot to take my heart rate monitor off and I made a startling discovery. Washing the car (hand and bucket method) gets the heart going smack bang in the middle of the fatmax zone. That explains why the ladies at bikini car washes always look so good and also makes you wonder about the link between water restrictions and the obesity epidemic....

here's a business idea for you Ev - start up a weight-watchers style guys topless car washing service - im sure you'd get some overweight volunteers and the laugh factor would bring in the customers. you might have to employ the 'crack-spackle' though ...

I have found not having a car, and being forced to walk further to the shops, bus stop etc makes a big difference, im also not in front of a computer 10 hours a day. I think Tennis is also good for that mid-level cardio exercise that lasts an hour+
